Lugol's Iodine Solution is the best way to provide Iodine & Iodide to the body's cells. It has been used successfully since its invention in 1829. Most Americans are deficient in Iodine based on government studies and that is based on a grossly inadequate RDA of only 150mcg. The Japanese consume over 100 times this amount and are far healthier in many key areas than Americans. Iodine is vital for all glandular function and structural integrity.
